To all whom it may concern:

Be it known that I, MORITZ BENON, a citizen of the United States, and aresident of the city and State of New York, have invented certainImprovements in Recording Mechanisms, of which thefollowing is aspecification.

This invention relates to certain improvements in recording mechanisms,and more particularly in that class or type of such mechanisms whichare. more especially designed and adapted for employment in theproduction of successive records upon record sheets or strips such asare commonly used in connection with monotype type casting machines andthe like, and the object of the invention is, in part, to provide amechanism of this general character having means of a novel and improveddescription for assuring the uniform and regulated supply of the recordsheet or strip to the recording means where such sheet or strip, as iscustomary, is supplied in roll form, wherebyinjury to the sheet or stripresulting from irregular or non-uniform unwinding of the same from theroll, and improper presentation thereof to the recording means,resulting in destruction of the feed apertures ordinarily provided, orinsufficient spacing of the successive records, are effectivelyprevented; in part to provide feed aperture producing means of a noveland improved description, for use in connection with recordingmechanisms such as are provided with feeding means engageablewith feedapertures in the record strip or sheet, where-,

by such feed'apertures may be produced in the previously unperforatedstrip or sheet in advance of such feeding devices or means to assuresubstantially perfect or absolute registry therewith and avoid not onlyloss of registry such as sometimes arises through expansion,contraction, or drying out of the previously perforated or aperturedsheets or strips commonly employed, but also the increased cost arisingfrom the expense involved in previously operating upon the sheet orstrip for the production of the feed apertures therein, and in part, toa special embodiment of my improvements as an attachment capable ofready and convenient application to recording mechanisms commonly inuse, so as to enable such mechanlsms to be improved by the addition ofeither the improved regulating or supplying means, or saidimproved feedaperture-producing means, or. both, without material change oralteration of the mechanisms as at present in use. 7

The invention consists in certain novel.

features of the construction, and combinations and arrangements of theseveral parts of the improved recording mechanism,

whereby certain important advantages are attained, and the mechanism isrendered simpler, less expensive, and otherwise better adapted and moreconvenient and effective for use, all as will be hereinafter fully setforth.

The novel features of the invention will be carefully defined in theclaims.

In order that my improvements may be i the better understood, I will nowproceed todescribe the inventlon with reference to the accompanymgdrawlngs, wherein- Figure 1 is a side elevation of a recording mechanismembodying my invention, showing the application of my improvements to amonotype or similar recording machine by way of example, my saidimprovements being herein shown constructed as an attachment for such arecording machine, and certain of the operative parts commonly providedin such machines being represented diagraphically Fig. 2 is an elevationof the parts shown in Fig. 1, as viewed from the rear, the suptachment,showing features of construction to be hereinafter referred to, theplane of Fig. 7 is a detached detail view also partly in section,illustrating features of the perforating means which will be hereinafterdescribed;

F 1g. 8 is a fragmentary detail view show- I ing the means for holdingthe perforators removably in place upon the carrier of the perforatingmeans; 7

Fig. 9 1s a fragmentary perspective view showing features ofconstruction of the bearings for the delivery roll of the attachment,

and a Fig 10 is a fragmentary sectional view showing features ofconstruction of the detent provided for retaining the removable rollholder in position in the attachment.

In these views I have shown my improvements embodied in an attachmentespe cially designed and adapted for use in connection with therecording mechanism of monotype type casting machines, but it will beapparent that the invention, while presenting important advantages whenembodied in such an attach1nent, is not limited to this specialapplication exclusively, but may with good results be constructed as anattachment for use in connection with machines of various other anddifferent kinds or if desired, may be embodied as an integral part ofthe machine to which the improved perforating device is to be applied.

The recording mechanism to which my improvements are herein shownapplied for use comprises a frame having spaced uprights, as 1, betweenwhich is supported for turning movement a driven feed sprocket 2,adapted for positive driving engagement with a record strip or sheet :0,usually of paper, which in the machine to which I have herein shown myimprovements applied is fed from a roll, ordinarily provided alongand-adjacent to its opposite lateral edges withnparallel series ofalined feed perforations, primarily formed in thestrip before itsapplication, in rolled form, to the recording machine, and adapted forengagement by thev teeth of the driven spcoket wheel 2 in such a manneras to permitthe latter to feed said strip accurately and intermittentlyto and between guides 3,3, having alined vertically directed aperturesadapted tobe traversed by a series of punches, as 4, which areselectively operated as will be hereinafter explained, to produce alongthe central part of said strip 00, between its oppositely arrangedseries of feed perforations, a perforated record conforming with thematter to be cast, so that after the completion of such record, saidstrip may be removed from the recording machine and applied to a castingmachine having matrix shifting and casting devices adapted for operationin asubstantially automatic manner under control of said record, to castthe desired matter in type form.

As herein shown, a chamber is provided between the frame uprights 1,adjacent to their lower parts, across which is extended a rock shaft 5adapted to be rocked in any preferred manner at each depression of anyone of the individual keys 6 of a key board which, insuch machines asordinarily constructed, comprises keys corresponding to the individualcharacters to 'be recorded, to-

gether with space controlling keys. The particular means employed foractuating the shaft 5 upon the depression of the several keys 6 isobviously immaterial to my invention. As herein shown, the desired operation is assured by the employment of a pneumatic cylinder 7, wherein ismovable a piston 8, the stem of which is coupled with an arm on shaft 5atone side ,of the frame, air under pressure being supplied to saidcylinder from a supply pipe 9, under control of a valve 10, coupled witha' universal bar 11 .operable'upon depression of either one of theseveral keys 6 at the, key board to open said valve and admit air underpressure to said cylinder beneath the piston 8 so as to elevate thelatter and rock the shaft 5 each time one of said keys (3 ismanipulated, a spring or the like being provided for retracting theparts prior to the ClGPIQSSlOlLOffllG next succeeding key.

The recording punches 4, are operated se' lectively from 01: in unisonwith therocking of shaft 5 under control of the individual keys 6 at thekey board was toproduce the desired record in accordance with the orderin which the individual keys are depressed, and the means'foraccomplishing this result are also immaterial to my present inventionand may be such as are ordinarily employed in monotype recordingmachines, operable upon the depresslon of any particular key 6 toactuate thecorresponding punch 4 exclusively from the rock shaft 5 insuch a manner as to produce the desired record perforation in the strip00 at an arbitrary point in the width thereof, as clearly indicated inFig. 5 of the drawings. The feed sprocket wheel2 will also be drivenintermittently in unison or time with the depressionof the keys 6 by anypreferredlmeans, in such a manner that a feeding impulse will beimparted to the strip 00 afterthe depression of each key 6, andcorresponding operation of the related perforating punch 4, so as topresent an unperforated part of said strip in position to be perforatedupon the next succeeding operation of one of said series of punches 4.

pared with plication to as at present muse, for whlch purpose 12,adapted to receive a detachable roll support, whereon is replaceablymounted a roll of paper provided for the production of 'the record, saidroll having been previously prefeed perforations parallel with itsopposite lateral edges for engagement by the teeth of the feed sprocket2, but in actual practice, certain disadvantages have arisen from theemployment of such previously formed perforations, either on account oftheir lack of registry with the teeth of the feed sprocket throughinaccuracy in the formation of said perforations as originally produced,or through expansion or contraction of the paper after their production,or

from other causes, besides which the production of the feed perforationsin the paper prior to its introduction into the machine is obviously amatter of greater or less expense, the avoidance of which assures animportant economy and advantage in the operation of such machines.

In carrying out my invention, in orderto avoid these disadvantages, Idispense with the preliminary perforation of the strip and supply anunperforated roll in lieu of the previously perforated roll commonlyemployed, said unperforated roll being supported in such a manner as topermit the un perforated strip or web of paper to be fed therefrom to aperforating device or means operable under control or in time with thekey and feed mechanisms in sucha way as to assure perforation of thestrip for the production of one or more feed perforations upon thedepression of eachkey of the key board or upon each successive operationof the recording punches 4, or of the intermittently driven feedsprocket, the perforating device employed for the production of suchfeed perforations being so constructed and arranged that theperforations are produced in the strip in accurate registry with theteeth of the feed sprocket so asto avoid tearing or injury to the stripdue to insuflicient registry, and said perforations being producedduring the operation of the recording mechanism, so as to avoid loss ofregistry due to expansion or contraction of the paper, and the increasedcost heretofore arising from separately operating upon the paper for thepreliminary production of the feed perforations.

In the emb diment of my invention herein shown, the improvedperforatingdevice is constructed as an attachment capable of apmonotyperecording machines the attachment is provided with a transverse shaft orsupport 14, the ends of which afford ournals removably engageable in thealined bearings 12, ordinarilyprovided for the reception of the rollsupport, so that the attachment may readily be applied to the machinewithout substantial or material modifi cation ofthe latter. This methodof connection of the attachment to the recording machine is obviouslynot material to my invention. I t

Between its journals, the shaft or support 14- is provided with alinedarms 15, 15 adjustably mounted thereon and having at their extremitiesalined bearings, in which is adjustably held by means of set screws 16,

or the like, a shaft or journal 17, extended transversely across theattachment between the spaced side frames 18, 18 thereof, to which saidshaft or journal is fixedly secured at its extremities, by which meansit will be apparent that the attachment is capableof a certain extent ofadjustment vertically so as to position its operative parts in anydesired relation to the feed sprocket 2 of the recording machine, itbeing apparent that angular ad ustment of the arms 15 with regard to theshaftsl and 17 is possible by proper manipulation of these parts andtheir set screws in such amanner as .to raise or lower the attachment.The journals of the shaft or support 1% may be secured against movementin the bearings 12, of the recording machine in any preferred way, if

this be desired as, for example, by means of nuts applied upon the endsof said shaft or support, and upon the spaced side frames 18, 18 of theattachment I have provided adjusting screws 18 engageable with thespaced frame uprights 1, to position the attachment in a horizontaldirection, it being apparent that by turning said screws they may becaused to project to a greater or less extent from the side frames 18 soas to position the operative parts of the improved perforatingattachment farther from or nearer to the feed sprocket 2 of therecording machine, as may be desired.

The outer sides of the side frames 18, 18 of the improved attachment areprovided at their lower parts with integral laterally 'projecting offsetlugs or shoulders 19, 19 vertically alined and spaced apart from eachother, cross bars or tie members 20 and 21 being attached at theiropposite 'ends thereto so as to extend transversely across the frame ofthe attachment at its lower part one above the other, the uppermost ofsaid bars or members, as 21, being as herein shown formed in upper andlower sections for convenience in the production between them of anarrow elongated passage 13 adapted to be traversed by the record strip190 as will be hereinafter explained.

At their upper ends the side frames 18, 18 of the improved perforatingattachment are provided with alined bearings 22 22 wherein are mountedadjustablepintles 23,

23 having tape-red orconica'l extremities :de- 7 tachably engageable inaxially alined recesses 26 at .the opposite ends of a removable rollsupport whereon the unperfo rated paper roll 00 is removably supported,as clearly indicated in the drawings, so that the strip 00 maybewithdrawn from said roll support gradually during the operation of theimproved perforating device.

For convenience and as herein shown, the roll support 25 is provided atonerend with a head or enlargement 32 affording an abutment againstwhich one end of the paper roll 00 is adapted to bear when applied uponsaid support, the other reduced end of said support being provided inone side with a longitudinal channel 33 wherein is secured a springretainer 33, the free extremity 34: of which is adjacent to the end ofthe roll support and is normally held by the tension of the springmaterial from which the retainer is produced, pressed outwardly from andbeyond the side of said support, so that an inclined or beveled surfaceupon said extremity 3% is presented for contact with the paper roll whenthe same is being applied to V the support, in order that the roll mayreadily he slipped in place upon the support over said beveled'surface,while a shoulder upon-said extremity 34 of theretainer at its sideopposite to said beveled or inclined surface operates by engagement withthe paper roll when the latter is in place upon the support, to preventwithdrawal of the roll therefrom except the extremity of the retainer befirst pressed down into the channel 33 as is permitted by its inherentelasticity.

One of the pintles 23 as herein shown is in the form of a screwlongitudinally adjustable in the bearing 22 of the corresponding sideframe of the attachment, so as to permit of being adjusted forpositioning the roll support and unperforated paper roll carried therebylaterally of the attachment if this be desired, a lock nut beingprovided upon said screw for holding the same in adjusted position, andthe other of said pintles 23 is formed as an'endwise movable bolt havingatone side a slot or recess 26*.extencled lengthwise in it, engaged by ascrew or'pin 27 upon the bearing 22 of the related side frame 18, saidpin or screw 27 operating as a stop to limit the endwise movement of thebolt and to prevent with drawal of the same from the bearing. 29represents a locking pin or detent pressed by a spring 30 endwise alongan aperture in the bearing 22 and having :a pointed extremity 31engageable with a conical recess in the side of the bolt or pintle 23 soas to hold the latter against endwise movement when in position toengagethe roll support 25, as clearly shown in Fig. 10. By withdrawing thedetent 29 against the tension of its spring, the bolt 23 maybe'disengaged from the roll support to permit requires to be replaced.

As herein shown, the lugs 19, 19 project laterally from the side frames18, 18 at that side o-fthe attachment which in operation is nearer tothe feed sprocket 2 of the recording machine, while at the opposite orrear side .of the attachment said side frames 18,v 18 are provided withintegral alined bearings wherein is supported for free rotation a guideroll 35 over which the unperforated paper strip 00 is adapted to besupplied, and in order to equalize the tension upon said strip duringits withdrawal from the roll as and delivery to said guide roll 35despite the intermittent operation of the feed sprocket 2 and thevarying resistance offered by the paper roll on account of its graduallydiminishing diameter, which is liable to tear the strip or its feedperforations,and to interfere with its gradual and regulated deliveryfrom the roll 00- I provide an equilizing means interposed between saidroll m and the guide roll 35 which as herein shown includes anequalizing roll 36 mounted to turn freely in the ends of arms 37pivotally supported at 38' upon brackets 39 securedtothe lower part ofthe spaced uprights 1, of the recording machine below the improvedperforating-attachment, or otherwise supported in such a manner that thestrip fromthe paper roll m may be drawn downwardly beneath saidequalizing roll 36 and thence be led upwardly to and over the guide roll35 in such a manner as to form a loop as indicated at m in the drawings,the roll 36 being capable of a certain extent of vertical movement insuch a manner as to tend to equalize the movement of, the strip as thesame is withdrawn from the roll x and to compensate for the intermittentfeeding impulses imparted thereto by the operation of the feed sprocket2 while at the same time equalizing the strain and pull upon said stripas the same is drawn intermittently through the improved perforatingattachment so as to avoid tearing of the feed perforations or breakageof the strip itself, as well as avoiding the unwinding from the roll 00of an excessive length of the strip such as would be likely to occurwere the sharp and sudden intermittent feeding impulses imparteddirectly to the roll 00 itself instead of'b'eingtaken up by the loop 92The length-of the loop w and LOO the precise manner in -which the sameis 7 formed are, of course, immaterial to my present invention. Asherein shown, one or both of the arms 37 which afford'pi-votal supportsfor the equalizing roll 36 have.

extensions LO with which are coupled springs 41 the tension of which isexerted to hold the roll normally depressed with an elastic pressurenicely calculated to compensate for the intermittent feeding impulses{during which the strip is drawn through the attachment.

As herein shown, the guide roll 35 is provided adjacent to its oppositeends with circumferential flanges or projections 42, 42 the innersurfaces of which are beveled or tapered in such a manner as to beadapted, by engagement with the opposite lateral edges of the strip a,to guide and center the same with relation to the feed sprockets of therecording machine and the perforating means of the improved attachmentas will be hereinafter explained, and 52, 52 represent springs whichbear upon the lateral or edge portions of said strip opposite to theguide roll 35 in such a manner as to retard the travel of the strip mthrough the attachment and to place a desirable tension upon the samebetween said guide roll 85 and the feed sprocket 21, in such a manner asto eliminate the likelihood of occurrence of any slack or looseness ofsaid strip such as might result in improper positioning or spacing ofthe feed perforations produced in said strip by the perforating meanswhich in the embodiment of the invention herein shown, operates upon thestrip during'its travel from the guide roll 35 to said, feed sprocket 2.An idler roll is also positioned in the attachment adjacent to the guideroll 35 to assist in directing the strip therefrom to the perforatingmeans which latter will presently be described. If'desired, this roll 70may be replaced by a fixed rounded bar or equivalent member, or may bedispensed with altogether.

From the roll or member 7 0 the strip 00 passes through the aperture 43hereinabove referred to between the upper and lower sections of, the'uppermost tie member 21, which aperture is made of dimensions sufficientto accommodate the free passage of said strip so that in its travelthrough the attachment the strip will be, held flush against the uppersurface of the lower section of said tie member by reason of the tensionexerted upon the strip by the operation of the leaf springs 52hereinbefore referred to, and above said uppermost tie member 21 andalso extended transversely of the attachment and of the stripstraversing the same is positioned a vertically movable punch carrier orsupport 45, alined with and normally spaced apart from said tie member21, its opposite end portions being provided with separately formeddetachably mounted punches 44, 44 the lower ends of which are pendentparallel with each other beneath said carrier 45 and are adapted totraveise vertical bores or passages 46 provided in alinement with eachother through the spaced upper and lower sections of saidtie member 21when said carrier or support is depressed, in such a manner as topenetrate the strip as within the aperture 43 and adj acent to itsopposite lateral edges for the production of the feed perforationstherein.

The proportions and arrangement of the parts, as herein shown, are suchthat when in their normal inactive or elevated positions, the lower endsof'the punches 44, 44, are engaged within the bores 46, 46 of the uppersection of the tie member 21, and stand above and out of position forcontact with the surface of the paper strip m traversing the aperture43, said upper section of the tie bar 21 actingas a stripper to compeldisengagement of the punches from said strip when the punches areretracted upwardly, so that said punches offer no interference to thefeeding movement of said strip during the intervals intervening betweensuccessive depressions of said punches, the alinement of the bores 46 ofthe lower section of the member 21 with said punches assuringpenetration of the strip lying flush upon said lower section when saidpunches are depressed, for the production of the feed perforations insaid strip and being traversed by the particles of paper removed fromsaid strip by said punches in theproduction of said perforations, whichparticles are thus discharged at the underside of the tie member 21.

54 represents a receptacle or drawer removably; positioned between thetie-vmembers 20 and 21, open at its top to receive the particles punchedfrom the strip and discharged at the underside of the upper member 21,said drawer being provided at its lower part with a spring retainer 55having a shouldered extremity 56 engaged beneath the lower tie bar 20 insuch a manner as to lock the receptacle or drawer securely thereto wheninserted between the members 20 and21. Upon depressing the shoulderedend of the retainer 55 to disengage it from beneath the member 20, thedrawer orwreceptacle may be removed" from the attachment to permit ofbein emptied whenever necessary. A handle 5% is provided upon the rearside of said drawer to facilitate its removal. I

' 47, 47 represent parallel guides connected with the opposite ends ofthe punch support or carrier and pendent beneath the same, their lowerparts traversing alined apertures in the lugsorprojections 19, 19 oftherespective side frames of theimproved' attachment, so as to be adaptedfor endwise movement therethrough, and being connected below thelowermost tie member 20 with the opposite ends of a cross head 48 whichis adapted for operation from or in time with the operation of theactuating ,means for the recording punches 4 of the monotype recordingmachine, by means which will be presently described, in such a manner asto depress the punch support or carrier 45 in order that its punches 44,44 may penetrate the strip a; for the production of feed perforationstherein at or for each individual actuation of the recording means, and49,

strip; at and housed within the bores 46 of the upper section of saidmember 21 to permit free feeding movement of said strip after eachpunching operation. As herein shown each of said springs has its upperend coupled with the lower end of a screw .50 which is passed through anaperture in the end of the tie member 21 and is engaged with a wing nut51 above said tie member by turning which wing nuts the screws may bemoved vertically to adjust or regulate the-tension of said springsindividually or jointly. r i

V 58 represents an auxiliary retracting spring secured at its centralpart to the underside of the punch support or carrier 45, and having itsarms bent downwardly in position to engage the uppermost tie member 21when the punches are depressed for the production of the feedperforations in the strip, whereby t'he upw ard' retraction of saidpunches and their disengagement from the strip is assured. prior to thefeeding move- 1 ment 'ofthe latter; 62, 62 represent adjustable stops,herein shown in the form of screws mounted adjacent to the opposite endsof the punch carrier or support 45, with their tipsprojecting beneaththe same and adapted for engagement with the upper tie member 21 of theattachment frame in such a way as to limit the descent of said puncheswhen the cross head 48 is actuated, and 63, 63 represent similaradjustable stops also in the form of screws carried adj ac'ent toopposite ends of said cross head and having their tips projecting abovethe same in position for engagement against the underside of the lowertie member 20 of the attachment frame in such a way as to limit theupward retracting movement of the parts and prevent the punches frombeing withdrawn completely from: the bores 46 of the upper section ofthe upper tie member 21 upon upward movement of the punch support orcarrier. By adjustment of these screws 62 and 63 the vertical movementsof the punches may be regulated at will.

As herein shown, the respective punches 44, 44 and their bores orpassages 46, 46 in the tie member 21 are distinctively formed or shaped,so as to be adapted for the production of distinctively different seriesof feed perforations along the opposite sides of the record strip w, andfor convenience in replacing or substituting said punches, I have hereinshown them detaohably secured to the carrier or support 45, forwhiohlpurengage the head 59 ofthe punch so as to hold the lattersecurely in place.

The means for operating the cross head 48 in time or synchronism withthe keys 6 of the recording machine key board and their relatedrecord-making punches 4, may obviously be of any preferred kind, but asherein, shown this means includes an adjustable connection pendent"below the central part of the cross head and adapted for connection atits lower end with 71 projecting rearwardly from the rock shaft 5, sothat at each rocking movement imparted to said shatt upon the operationof one of the keys 6, the cross head is drawn downwardly and the'punches44, 44 are caused to penetrate the paper strip a for'tlie production ofthe feed perforations therein. As hereinshown, the actuating connectionemployed includes upper and lower members-or stems 72, 72, alined witheach other, one of said stems or members being apertured'at its upperend for the passage of a removable pin or bolt 74, which traversesspaced apertured lugs centrally produced upon the underside of the crosshead so as toafl'ond detachable connection therewith, while the lower ofsaid stems or members .72 is provided with a head or the like engagedbeneath the arm 71 of the 7 rock shaft 5 so that when said arm isdepressed upon the rocking shaft ensulng upon depression of either ofthe keys 6 at the key board, the cross head '48 is also drawndownwandly, together with the punch carrier or support 45, to cause thepunches 44, 44 thereof to penetrate the record strip for the production.of the feed perforations therein. The actuating connection alsoincludes a central member 73 with which each of said stems or members72, 72 has jointed or universal connection, nuts being provided uponsaid members or stems 72, 72 engageable above and below the centralmember 7 3 by which means the connection may be adjusted lengthwise to[assure proper operation of the improved perforating attachment.

By this construction and arrangement of the parts it will be apparentthat whenever a key 6 at the key board of the recording machine isdepressed, the mechanical or other suitable connection of the punchactuating cross head 48 of the improved attachment with the recordingmechanism will assure the operation of the punches 44, 44, to producefeed perforations in the record strip w immediately in advance of thefeed sprocket 2, and said punches being 'alined with the teeth of saidsprocket and the strip held with a uniform tension during the productionof said feed perforations, it will be apparent that absolute registry ofthe feed perforaions with the sprocket teeth will be assured and thepossibility of loss .of such registry due to expansion or contractionof'the strip will be entirely done away with, while at the same time amaterial economy is attained by reason of the avoidance of any separateoperations such as have heretofore been necessary for the preliminaryperforation of the record strip.

After the depression of each key 6 at the key board of the recordingmachine, the feed sprocket 2 being actuated in the ordinary manner,serves to feed or draw the rec- 0rd strip not only past the recordforming punches 4, but also to draw or feed said strip to exactly thenecessary extent past the punches 44, 44 ment, so that the spacing ofthe feed perforations produced upon successive operations of the punches44, 44 will conform accurately to the toothing of the feed sprocket inorder that the likelihood of subsequent tearing of the feed perforationsmay be avoided, while at the same time the employment of the equalizingmeans including the looping roll 36 between the paper roll 00 and theguide roll 35 avoids excessive unwinding or jerking of the strip fromthe paper roll incident to the intermittent character of the feed, aswell as such pull or draft upon the strip as might interfere withuniform operation of the tensioning means 52 or result in tearing of thefeed perforations.

The employment of the equalizing means including said looping roll 36also permits of using in the recording machine a paper roll ofconsiderably greater diameter than is possible of employment where suchequalizing means are omitted, it being apparent that where the stripisunwound from said roll in a graduated and regular or comparativelycontinuous manner, irrespective of the intermittent character of thefeed, the roll may be of much greater size than is possible ofemployment where, as heretofore, the feeding impulses are imposeddirectly upon of the perforating attachthe roll to unwind the sameintermittently. It will thus be apparent that the equalizing means ispossessed of advantages and'functions which may in some cases render thesame desirable for employment independently of the improved perforatingmeans, and for this reason I do not desire to be understood as limitingmyself to the use of said equalizing means exclusively in connectionwith the perforating means herein shown. i i

In order to. deliver the perforated strip accurately to the feedsprocket 2 of the recording machine from the perforating meansincludingthepunches 44, 44, I- have herein shown the improved attachmentprovided' with a delivery roll or member herein shown provided Withspaced plural rubber or other surfaced enlargements 64, 64, over whichthe perforated strip 00 is adapted to pass to the feed sprocket 2, saidenlargements being alined and adapted for contact with or pressure uponthe toothed parts of the .sprocket wheel so as to assure the delivery ofthe newly perforated strip or web thereto. The rubber surfacedenlargements 64, 64 are spaced to engage the strip 00 in line with thefeed perforations thereof and their yielding surfaces permit thepenetration of the. teeth of the feed sprocket slightly thereinto toassure registry of said teeth with the ,feed'perforations of said strip.

As herein shown the delivery member has reduced portions affordingjournals which are mounted to turn freely in open bearings 66, 66 uponthe bent forward ends of carriers 67, 67, mounted upon the respectivespaced side frames 18, 18 of the attachment, and capable of adjustmentlengthwise or to ward and from the feed sprocket to permit ofpositioning the-delivery roll or member at a greater or less distancebeyond the frame of the attachment and thus assure proper delivery ofthe newly perforated strip to said sprocket. The side frames 18, 18 areherein shown provided with slots 68, 68 traversed by bolts or screws 69on the carriers 67 67, which screws or bolts may be loosened to permitendwise adjustment of the carriers or tightened to hold them in adjustedposition. The adjustability of the delivery roll, and the variousadjustments hereinbefore referred to whereby the attachment frame may bedesirably positioned upon the frame of the recording machine arefeatures of material importance in the em-' tion it will be apparentthat the improved perforating device constructed according to myinvention is of an extremely simple and comparatively inexpensivenature, and is particularly Well adapted for use by reason not only ofthe economy attained by dispensing with the employment of previouslyperforated paper rolls for the production of records, but also by reasonof the accuracy with which the perforations are produced in the recordstrip without liability of loss of registry through expansion orcontraction of the paper, and the avoidance of liability of tearing orotherwise impairing the feed perforations or breaking the strip due tothe employment of the improved equalizing and tensioning means, and itwill also be obvious from the above description of myinvention that thedevice is susceptible of considerable modification without materialdeparture from the principles and spirit of the invention, as defined inthe appended claims, and

for this reason I do not desire to be understood as limiting myself tothe precise formation and arrangement of the several parts of the deviceas herein set forth in carrying out my invention in practice.

Having thus described by invention, what I claim and desire to secure byLetters Patent is: V r

1. In recording mechanism, the combination of recording means, drivenfeeding means for impelling a record sheet past said recording means andincluding a member engageable with feed apertures in said sheet, andmeans actuated simultaneously with said recording means, operable toproduce, said feed apertures in said sheet.

2.
